To all whom it may concern:

Be 1t known that we, EDWIN T. GREEN- FIELD and JOHAN GUs'rAr V. LANG, citizens of the United States, and residents, respectively, of Kiarnesha, county of Sullivan,

State of New York, and of the borough of Manhattan, cit of New York, county and State of. New ork, have made certain new and useful Inventions Relating to Apparatus for Contracting Rings, of which the following is a specification.

The invention relates to an apparatus which'is particularly adapted for the manufacture of paper bottles.

In the manufacture of paper receptacles it is .desirable to fixedly secure in place upon the paper receptacle as it is being made a clamping ring which'is U-shape in cross section. In actual practice, this ringjis preferably made so that one leg of the is longer than the other whereby the paper can be clamped between the legs when they are forced toward each other in a manner to cause a natural bend or set in the paper.

The apparatus which is shown in the drawings is particularly adapted for use in securing a bottom member in place in the body member of a bottle by means of a.

clamping ring of the class just referred to and which ring is pressed in such a manner as to maintain a hquid-tight joint between a flange on the bottom and the bod member of the bottle which are clampe or secured together by the ring.

As showing a specific embodiment of the invention reference is made to the drawgs forming a part of this specification, in which drawings,

Figure 1 is a vertical sectional view of the press. In this figure the ring which is to be operated upon is also shown. This figure is a view taken alon the line 1-1 of Fig. 4.

are shown in the position which they occupy at the end of the preing operation.

Fig. 4 is a plan view, partially broken away, of the press. This figure is drawn on a smaller scale than Figs. 1 to 3.

Figs. 5 and 6 are, respectively, plan and vertical sectional views of the expansible and contractible spring-ring which is utilized in the press.

Fig. 7 is a vertical side view, partially broken away, of an assembled bottle body and bottom prior to thebottom clamping ring being placed upon it.

1 1g. 8 is a vertical side view, partially broken away, showing the clamping ring which is utilized to secure the bottom of the bottle to the body portion of the bottle.

Fig. 9 is a vertical view, partially broken away, of the lower portion of the bottle. This view shows a clamping ring after it has been compressed-so as to securely clamp the bottom and body portion of the bottle together in a manner to make a liquid-tight joint.

The press comprises any suitable frame member as 1 to which there is secured in a suitable manner an anvil or resisting member 2. This anvil member is positioned on the frame by means of a projecting portion 4 which enters a socket 5 and screws 6 are provided to secure the anvil in place. An expansible and contract-ibis ring 7 surrounds the anvil. This rin is of a springy material and is in the orm of a spiral; it is supported by a series of hammers or pressing members 8 that surround the ring. These hammers are carried by or mounted upon the frame 1 as by depending portions 9 which enter an annular socket portion 10 of the frame. These hammers are mounted so that they, or: at least their u 'per ends, can move inwardly and outwa y in a radial direction, their inward movement being accomplished through the medium of a ring or sleeve 11 which surrounds them. This sleeve 11. has a dim 12 which engages cam portions 13 at are located on the outer sides of the.hammers,and from an tion of the drawings it is manifest that w on the sleeve-11 is forcedupwardly the ham- .mers be-forced inwardly by the en-y for gagement of the' portion 12 on the sleeve with the cams 13 on the hammers. The upward movement of the sleeve 11 is acoomplished through'the mediuinof a lever 14 which is fulcrumed on the frame at 15 of coils so that the spring will entirely surhas. an internal extendin round the anvil at all points. This spring projection or shoulder 18. The upper en s of each of the hammers or pressing members extend inwardly and downwardly so as to serve as a guiding means whereby the'work will be readil placed inposition in the machine. It willlbe noted that the lower ends of these iding means extend inwardly beyond the inner ed e of the to portion of the expansible an contractib e ring 7.

The press is constructed so that a solid or continuous ringFM' whichds U-shape in cross section see ig. 8) can be placed in the press in t e manner shown in Fig. 1. The assembled bottle body member and bottom are then placed in the machine, as shown in Fig. 2, in a osition so that the lower edges of the bott e body and the depending flange -of the bottom will enter the cavltary portion of the 14 is then 0 rated so that t e hammers and expansib e and contractible ring will be caused to assume the position shown in Fig. 3. In other words, as the parts are forced to the position shown in Fig. 3 it will be ebserved that the hammers orressing members have been movedinwar y in a manner to cause the rin 7 to contract and as the ring contracts the individual coils in it have a slight sliding movement relative to each other and also relative .to the ring being pressed, thus tending to iron out any crimps which 'form in'the outer le of the ring M. It will thus be noted t at the spiral ring 7' rforms the pressin and forming operation and hence may referred to as a! ressing' or a forming ring.

It will furt ermore be noted that the shoulder 18 of the ring is arranged relative to the free edge of the short inner leg -X so that the shoulder will enga only that pgrtion of the outer leg- Y w ich extends yond or above the free end of the shorter leg. .The anvil 2 serves as a resisting mem her to support the shorter or inner leg while 2110 u per end of the outer, leg is being The lever anvil and inwardl 5.
